ANCHOR roza FLOOR SLEEPERS.

vApplication filed October 21,1927. Serial No. 227,670.

The main objects of this invention are to provide an improved form ofbar support; to provide an improved bar support and spacer particularlyadapted for use in concrete construction work; to provide, a device ofthis kind which is particularly adapted for use in supporting floorsleepers; to provide improved means for anchoring the supporting meansin the concrete; to provide improved fastening means for securing thesleepers to the supports; and to provide a device of this kind whichcombines the supporting, anchoring, spacing and fastening means in adurable unitary structure, wherein the joint between the anchoring andspacing means is spaced from the fastening means so as not to be brokenwhen the fastening means are bent into engagement with the sleeper.

Illustrative embodiments of this invention are shown in the accompanyingdrawing, wherein:

Figure 1 is a vfragmentary vertical section of a concrete slab on whicha sleeper is supported by means of an improved anchor, the dottedoutlines representing the fastening means in their operative positions.

Fig. 2 is a perspective of a sleeper supported on the anchoring deviceshown in Fi 1.

' Fig. 3 is a fragmentary perspective of one of the anchors shown inFig. 2.

Figs. 4 and 5 are views similar to Fig. 3, but showing modified forms ofanchors.

In the forms shown, the improved anchors are used for supporting floorsleepers or bars 1 on a concrete slab 2. Floor sleepers are generallydisposed in substantially pare allel spaced relation to one another toform a wooden frame structure to which the customary floor boards arenailed. V

In the embodiments illustrated, the improved anchoring devices comprisea spacing member having secured thereto a supporting member providedwith anchoring portions adapted to be embedded in the concrete andhaving fingers forming fastening means for attachment to'the sleeper.The improved anchoring devices may be made of any suitable material butare preferably formed of wire rods which may be bent to the desiredshape.

In the form shown in Figs. 1, 2 and 3,

each of the devices comprises a spacing rod 3 having a plurality ofsupporting members 4 secured thereto at regular intervals.

vices, the fastening Each of the supporting members 4 comprises a pairof substantially V-shaped anchorlng portions 5 arranged in substantiallythe same plane and having their inner legs connected together by a shelfportion 6, which is spot-welded or otherwise rigidly secured to thespacing rod'3. The outer legs 7 of the anchoring portions 5 arepreferably disposed substantially parallel to each other as shown inFig. l.

The outer legs 7 of the anchoring portions 5 are longer than the innerlegs, so as to provide fingers 8 adapted to embrace the sleeper 1.Formed at the outer ends of the fingers 8, are eyelets 9 to receivenails 10, which are driven into the sides of the sleeper for securingthe latter to the anchoring device. In the manufacture of these improveddevices, the fingers 8 are bent downwardly, as shown in full outline inFigs. 1 and 3, with the bend 11 located slightly beyond the spacing rod3, so as to necessitate straighten ing of the fingers in attaching thesleepers.

In certain anchoring devices heretofore in use, the fastening fingerswere welded to the spacing rod at the pointof, bending. Such deviceswere objectionable mainly because, in straightening the fingers intotheir operative positions, the welded joint was frequently broken. Inthese improved defingers 8 are not connected to the spacing rod 3 andtheir base portions are free to move alimited distance relative tothespacer. With this improved arrangement of parts, there is no possibilityof breaking the welded joint between the members through the bending ofthe fingers.

The shelf 6 and the portion of the spacer 3 which is located between thefingers 8 provide a seat for the sleeper and this seat may be varied insize by ward or away from each other.

In the construction shown in Fig. 4, the device comprises a spacing rod12 having secured thereto supporting members 13 of modified form. Themember 13 comprises a wire rod bent to form a pair of anchoring portions14 arranged in different planes and connected by a shelf portion 15which is P disposed at substantially right angles to the spacer 12. Inthis construction, the outer legs of the anchors 14 are located insubstantially the same plane and are provided with fingers 16 similar inform and arrangement to those shown in Figs. 1, 2 and 3. I

The device shown in Fig. 5 comprises a moving the fingers to- V spacer17 having secured thereto a plurality of supporting members 18 which aresubstantially similar to the one shown in Fig. 4. However, in themodification illustrated in Fig. 5, the spacer 17 is disposed atsubstantially right angles to the supporting members 18 so as to extendlengthwise of the shelf portions 19.

In operation, after the concrete has been poured and before it has set,the improved anchoring devices are placed on the slab with theanchoring. portions embedded in the concrete and the spacers resting ontop of the slab as shown in Fig. 1. The devices are arranged so as toposition the spacers in substantially parallel relation to one anotherat the desired intervals. After the concrete has set, the sleepers areplaced on the seats defined by the flexible fingers and the latter arethen bent upwardly to embrace the sleepers so as to permit the nails tobe driven into the sides of the sleepers. In the forms shown in Figs. 1,2, 3 and a the sleepers are disposed at substantially right angles tothe spacing rods, whereas in the form shown in Fig. 5 the sleepersextend longitudinally of the spacers. I
